First step is to get it to work via 'R CMD INSTALL ...' and the Debian
wrapper come thereafter.
Thanks a lot Dirk for putting me in the right direction!
So I persevered a bit more with src/Makevars and ran R CMD INSTALL from
outside Debian's build system first, which leads me to figure out that
src/Makevars was unconditionally overwritten by the ./configure script.
Patching this file allowed me to inject -fsigned-char in the build.
I will upload this soon and hope it fixes the issue on arm64 and the like.
Have nice day!
